﻿144 BRITISH BEETLES. 



Tehnatophilus, also, is found upon plants, especially 

 near water : its tarsi are pentamerous, with the fourth 

 joint almost obsolete ; the second and third being bi- 

 lobed (the latter very strongly so), and the two first 

 densely pilose beneath. 



The prosternum has its hinder part projecting, and 

 received into the anterior margin of the mesosternum, 

 which is nearly square. The antennse are eleven-jointed, 

 with a small three-jointed club ; the mandibles are 

 finely denticulated before their extremity ; the eyes are 

 round and large ; and the body slightly pubescent. The 

 species are all small, and rather narrow. 



The conflict between the facies, habits, and structure 

 of the tarsi, etc., in these insects makes it difficult to 

 locate them with any certainty. 



The Clerid^ (which are mostly brightly coloured) 

 have the antennae often clubbed ; the labrum distinct ; 

 the tarsi provided with lamellae beneath and sometimes 

 bilobed ; often only five abdominal segments ; the pos- 

 terior coxae transverse, sunk, not approximated, and 

 covered by the hind femora; the body oblong, usually 

 cylindrical, rather hard, and hairy; the eyes kidney- 

 shaped and notched ; and the head and thorax narrower 

 than the elytra. They are remarkable, also, for usually 

 having the labial larger than the maxillary palpi. 



In Tillus, Clerus, Opilus, and Trichodes there are five 

 joints to the tarsi, and the pronotum is confused with 

 the prothoracic parapleurae, so that the thorax becomes 

 cylindrical ; but in the sub-family Enopliides, to which 

 the genus Corynetes belongs, there are only four joints 

 (the normal fourth joint being imperfectly developed); 

 and the upper part of the thorax is separated from the 

 sides by a more or less conspicuous ridge.
